training: Exercise RIMPAC 1984. We hitched a ride aboard an LSD out to Pearl Harbor and then set up in the mountains, in a defilade position, above Hanauma Bay, Oahu.



Above: The AN/TSQ-108 set up at Red Beach, Camp Pendleton CA. Lots of interesting things to detect, localize, identify, record, analyze, track, see, hear – and prosecute. Got antennas?
